memmove(3)                 Library Functions Manual                 memmove(3)

NAME
       memmove - copy memory area

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #include <string.h>

       void *memmove(void dest[.n], const void src[.n], size_t n);

DESCRIPTION
       The memmove() function copies n bytes from memory area src to memory
       area dest.  The memory areas may overlap: copying takes place as though
       the bytes in src are first copied into a temporary array that does not
       overlap src or dest, and the bytes are then copied from the temporary
       array to dest.

RETURN VALUE
       The memmove() function returns a pointer to dest.
